NUT-LOCK.

Specification of Letters Patent.

Patented Apr. 39, 1918.

Application filed August 24, 1916. Serial No. 116,586.

To all whom it may concern.-

Be it known that I, LOUIS A. MEIER, a citizen of the United States, residing at Devils Lake, in the county of Ramsey and State of North Dakota, have invented certain new and useful Improvements in Nut Locks, of which the following is a specification.

This invention relates to nut locks and the object of the same is to provide an improved form of nut locking means that will positively secure a nut from accidental rotation however, allow for the same to be quickly and easily released so that it can be removed from a bolt at will.

Another object of this invention is to provide a nut locking device that will not destroy the threads on which the nut is threaded yet positively prevent the rotation of the nut on the bolt when the locking ieans is in. position.

A still further object of this invention resides in the production of a device of the kind above described that is simple in corn struction, efficient in operation and consists of the minimum number of parts.

With these and other objects in view, this invention consists of certain novel constructions, combinations and arrangement of parts, as will be hereinafter fully described and claimed.

In the accompanying drawings:

Figure 1 is a view in elevation of the device.

Fig. '2 is a top plan view of the device .S lTJWH in Fig. 1.

Fig. 8 is a section taken on line 3-3 of Fig. 1, and

Fig. 1- is a detail perspective view of the locking key used with this device.

morals, a portion of the bolt is designated by the numeral 10 and the threaded end thereof by the numeral 11. Anut is designated in its entirety by the numeral 12 and ceiving bore 13. A diagonally extending here let is formed in the nut and runs from one side face of the same and communicates with the bolt receiving bore 13. A second bore 15 is formed in the nut, the same communicating with the first menlcfcrring to the parts by reference nutioned bore 14. A locking means is adapted to be inserted in the bore 14 in the nut and the same is designated in its entirety by the numeral 16. This key 16 has the inclined side faces 17 that terminate in the beveled face 18 forming a sharp edge for engagement with the bolt. served, by reference to Fig. 3, that the bore 14 in the nut 12 is of such shape as to receive the key 16 and the side walls of the bore 14: are engaged snugly by the inclined sides 17 of the key to limit the inward movement of the key.

An opening 19 is formed in the key 16, the same adapted to be placed in alinement with the bore 15 formed in the nut when the key is inserted as shown in Figs. 1 and 3, and a means, a cotter pin, designated by the numeral 20 is adapted to be passed through the bore 15 and the opening 19 in the key 16 to retain the key in a position as shown in the drawings.

It is to be observed that the inward movement of the key 16 in the slot is limited by means of the engagement of the inclined faces 17 of the key with the side walls of the bore into which the same is threaded and thus the opening 19 in the key is always retained in alinement with the bore 15 in the nut for the insertion of the pin 20 therethrough. a

It is obvious that minor changes may b made in the form and construction of this invention without departing from the material parts thereof. It is therefore not wished to confine the invention to the exact form herein shown and described, but it is wished to include all such as properly come within the scope claimed.

I claim In combination with a bolt, having a threaded end thereon, of a nut on said threaded end having a bore having inclined side walls, said nut provided with a second bore extending therethrough communicating with said first mentioned bore, a key for insertion in said first mentioned bore for engagement with said bolt to prevent the independent rotation of said nut ,on said bolt, said key having inclined side faces for engagement with the inclined side walls of said first mentioned bore to limit the in- It is to be Ob- Ward movement of said key, said key pro- In testimony whereof I afiix my signature vlded W1th an opening formed therethrough in presence of two Witnesses.

adapted for alinement with said second LOUIS A. MEIER. mentioned bore and a means in said second 5 mentioned bore and in said opening in said key to retaln said key 1n said nut.
